WILLIAM KANE, OF PHILADELPHIA, PENNSYLVANIA.

STEAM OR HOT-WATER GENERATOR.

SPECIFICATION forming part of Letters Patent No. 686,900, dated November 19, 1901.

Application filed March 18,1901. Serial No. 51,588. (No model.)

T0 at whom it may concern.-

Be it known that I, WILLIAM KANE, of the city and county of Philadelphia, in the State of Pennsylvania, have invented an Improvement in Steam or Hot-\Vater Generators, of which the following is a specification.

Myinvention relates to steam and hot-Water generators; and it consists of the improvements which are fully set forth in the following specification and are shown in the accompanying drawings. 7

One object of my invention is to provide a generator for generating steam or hot water adapted to raise the temperature of the water quickly and with the expenditure of a moderate amount of gas or fuel.

It is also an object of my invention to enable the generating capacity of the generator to be easily and quickly varied to suit the requirements.

It is also an object of my invention to provide a construction of generator of reasonably large capacity which may be easily and quickly erected or wholly or partially dismantled for purposes of repair.

In carrying out my invention I form the generator of a series of independent vertical generating sections or parts, each of which may be independently provided with heat from gas or fuel, so thatall or any number of the sections may be used.

In the preferred embodiment of my invention the generatingsections are formed of a series of vertical water-tubes having hea tingflues extending longitudinally through them for conducting the heat. Each section is inclosed in an outer casing adapted to localize the heat from the burner of that section and confine it to the water-tubes thereof. The several sections of the series are connected with and supported by a common dome or chamber and are inclosed by an outer casin g.

My invention embraces improvements in the construction of the independent sections and in the manner of' connecting the watertubes and heat-fines to the heads thereof and also embraces various improvements and combinations of parts, which are fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of a steam or hotwater generator embodying my invention.

Fig. 2 is a horizontal sectional view of the same on the line A A of Fig. 1. Fig. 3 is a similar view, enlarged, of one of the generating-sections. Fig. 4 is a vertical sectional View, enlarged, ofa part of one ofthe generating-sections. Fig. 5 is a plan view 0t one of the burners, and Fig. 6 is a horizontal sectional View on the line B B of Fig. 1.

The generator consists of a series of vertical generating-sections a a a a 850., communicating with a common dome or chamber b at the top and inclosed in an outer casing a. Each generating-section is composed of hollow ends (1 d, united by a series of circulating-tubes a, through which extend heatflues f, opening at the top and bottom through the hollow ends or heads cl (1. The heads (I d are also preferably united by a central tierod 01 The upper head cl of each generator communicates with the, dome or chamber 1) through a short connecting-tube g. The lower heads d are each connected by a pipe h with the inlet or return.

i is a central support carrying the dome b and having a base or pedestal i, resting upon or secured to the floor. I prefer to make this centralsupportt' hollow, in the form of a circulating-tube, as shown, opening at the top into the dome-band, communicating at the bottom with the return-pipe j, and with the bases of the generating-sections through the pipes h. i

The number of generating-sections a a, &c., employed and the number of circulating-tubes e in each generating-section are not material to the invention. I have shown six generating-sections arranged in a circle about the central support 1' and six circulating-tubes e in each generating-scction; but these numbers and the arrangement may be varied.

Located below each generatingsection is a burner 7c, adapted to supply heat to the lines f. These burners preferably consist of annular pipes having a cross-bar 7c, carrying a screw k adapted to be screwed into a threaded socket in the base of the generator, which,

may be conveniently formed in end of the tierod d or the tie-rod may be extended in a threaded end and the burner screwed upon it. (See right-hand side of Fig. 1.) In this manner the burners maybe easily applied or removed and their positions adjusted. The

burners k are connected with the supply-pipe Zin any convenient manner. As shown, an annular supply-pipe within the outer casing c is employed, with which the burners are connected by suitable couplings Z. Each burner may be controlled by a separate valve Z and the outer casing a may be provided with openings 0 adjacent to the valves to supply air to the burners and to afiord access to them for the purpose of lighting them, &c.

The generating-sections a a, 850., are preferably constructed as follows: On the inner 2'. a, opposingfaces of the heads d d apertures are formed of a proper diameter to receive the circulating-tubes e, and in the outer faces concentric with each of these apertures is formed an aperture 'm. of a slightly-larger diameter. The ends of the tubes 6 are inserted in the inner apertures and are expanded therein, this being permitted through the apertures m. Threaded plugs n, provided with apertures for the flues f, are then screwed into the apertures m, the fluesfare inserted through the apertures in the plugs, and their ends are expanded therein. This construction is clearly shown in Fig. 4. One end only is shown, as the other is similar.

To thoroughly localize the heat from each burner at the corresponding generating-section, I inclose each generating-section in an outer cylindrical casing 0, the ends of which encircle the heads 61 d, and by making the peripheries of the heads corrugated, as shown,

I provide vertical heat-flues pp between the outside of the tubes 6 e and the casing 0. Thus the heat from the burners is localized at each corresponding generating-section and is conducted not only through the internal fluesf within the tubes, but also through the flues or passage-ways p p on the outside of the tubes.

The products of combustion may pass off from the interior of the generator through a suitable flue 1'. All or any number of the generating-sections may be used as the condition may require. The water in the heads 01 d and tubes 6, heated by the products of combustion from the burners 70, will circulate through the connections 9 into the dome b,

and thence through the pipe 8 to the system, returning by the pipej and passing back into the base-heads d of the generating-sections by the pipes h. When the central support 73 is hollow, as shown, a portion of the Water will circulate through this support into the dome b, and thence into the pipe 8.

When the generator is used for steam generation, the steam from the dome b will pass into the pipe .9 and the water of condensation will return through the pipe j.

The details of construction shown may be varied without departing from my invention.

What I claim as new, and desire to secure by Letters Patent, is as follows:
